Tub Works® Bath Color Fizzies®, 150 Count, 3 Pack | Nontoxic & Fragrance-Free | Color Bath Drops Create Fun Bath Colors | Bath Color Tablets in 7 Colors for Variety | Bath Bombs for Kids Bath

I have been buying these for years now. It takes several tablets to really color the water, but that's part of the fun because you can mix and match and it helps teach about colors in a creative way. You can color your arm, hold them in your hand, and then it rinses right off with no residue in the tub afterwards. No fragrance and hasn't bothered anyone's skin or eyes. A fun bath toy all around.

This is the best product of this type that I could find. I tried 4 different brands and this one superseded the rest by far.My favorite features:- fast dissolve- vibrant color- easy to wash off from tile without leaving any trace- easily cones off fingers and body parts.

These are so much better and more affordable than those unpredictable Crayola ones.These provide a lot of color, they dissolve consistently, and there are a ton of pellets for the price.Cons: 1. they seem to give more yellow than any other color. 2. The Indigo and Violet are identical. Both purple. (But there is a true blue color)

These have been a staple for bath time for my kids. Pair this with the Learning Resources Splashology! Water Lab Science Kit and they will be so entertained they won't want to get out of the bath. The colors are fun, haven't stained any of our surfaces and you get so many! We have purchased multiples times and probably will again. Can also be used for fun water table play.

I think this is my most re-purchased item on Prime. Can make cool color combinations in the tub and teach kids about color theory. Really doesn’t stain the tub unless you let them sit on a damp area for a day.

Weak colors, but kids have fun and I'm not worried it could strain the tub

This is the perfect bath time toy for kids. We have cups where we add color drops together and my kids are always asking what the addition of another color drop is going to do to their colorful "potion" - this is truly a fantastic bath time activity.

My toddler loves these so much! He asks to take a bath all day long so we sometimes take 2 a day just so he can "make experiments" with these! He loves to mix colors with pipettes and beakers as well as random plastic containers! These have helped teach him about primary and secondary colors! We also use these in the snow too! We got spray bottles and eye droppers and he had a blast! These also smell fresh and have never irritated his skin, I highly recommend these!
